We missed a rather significant bit of architectural news in our green building posts last week. The “largest solar-powered office building in the world“ was recently completed in Dezhou, China. The design of the Sun-Moon Mansion is based on the sun dial and “underlines the urgency of seeking renewable energy sources to replace fossil fuels.” Aside from the obvious sustainable nature of the solar panel-clad exterior, other green features include advanced roof and wall insulation practices resulting in an energy savings of 30% more than the national standard.
